EVGA GeForce GTX 1080 SC Gaming ACX 3.0 vs Palit GeForce GTX 1080 GameRock Premium Edition

The EVGA GTX 1080 ACX 3.0 uses its own built-in cooling system which includes two fans. The ACX 3.0 cooler has been used on a lot of high-end graphics cards, and the GTX 1080 by EVGA is no different. In an idle situation, the EVGA GTX 1080 generally reaches temperatures up to 56° Celsius. At a first glance, that's pretty high, but the fans don't start spinning unless a temperature of 60° is reached. During full load, the EVGA GTX 1080 chip heats up to a maximum of 75 degrees Celsius - eight degrees cooler than a reference (Founders Edition) GTX 1080.

The maximum temperature of 75° C also means that throttling doesn't occur with the EVGA GTX 1080 SC Gaming ACX 3.0, something that tends to occur with other GTX 1080 cards with worse coolers. In other words, the graphics card won't slow itself down in order to stay cool: performance will be 100% at all times.

The GTX 1080 SC Gaming ACX 3.0 is a virtually silent card. In a non-gaming idle situation, the two fans of the cooler don't spin up at all - the card stays completely inaudible up to temperatures of 60° Celsius. Even during full load and intensive gaming situations, this edition of the GTX 1080 is remarkably quiet and stays under 40 decibels (when measured two inches above the motherboard in an open environment). For comparison: the reference GTX 1080 produces 45.5 dB of noise. Annoying coil whine sounds are not present in this edition either.

The GTX 1080 SC Gaming ACX 3.0 features a higher clockspeed compared to a reference GTX 1080, which means it has been factory overclocked to reach higher framerates and overall better performance. The base clock speed has been set at 1708 MHz, which is a 6.3% increase compared to the reference 1607 MHz. The boost clock has also received a factory overclock to 1847 MHz compared to the standard 1733 MHz, a difference of 6.5%.

This results in a slightly better performance, although practical performance differences aren't as noticeable. For example: In Rise of the Tomb Raider at 1080p and maximum settings, the SC ACX 3.0 is nearly 5 FPS faster than a regular GTX 1080. In the benchmarking suite 3D Mark Fire Strike Extreme, a GTX 1080 with reference clock speeds achieves a score of 9,387 points while the EVGA Superclocked takes the crown at 9,622 points. Although the performance differences between this overclocked card and a reference GTX 1080 are minimal, the extra power is nice to have nonetheless.

The EVGA offers the most performance for the dollar, and is $100 cheaper than almost any other decent GTX 1080 card. It has a great cooler, and comes with a decent clock speed without compromising the noise the card makes making it a well balanced option.

As it only requires 1 8 pin connector, it draws much less power for those whom may not have a high wattage rating power supply. Making this more eco friendly when it comes to energy usage.

The GameRock Premium Edition is priced at $629.99. For that price it offers pretty good performance. It achieved a 3DMark Firestrike score of 20,014 and averages at 127-133 FPS with the latest games such as Fallout 4 and Hitman at Full HD resolution.

When the fans are at their minimum, which is when the card is at about 60 degrees C, the noise level is at 33dBA, virtually inaudible unless you put your head next to the case. Under heavy load when gaming, the fans will generate noise at about 38dBA, which is a barely audible hum.

The large size and the twin 95mm fans it's equipped with help a lot with keeping the card cooled. The fans will also switch off at low load which helps with the noise levels as well. The I/O plate has a honeycomb plate to help with the ventilation which again, greatly contributes to the overall cooling performance of the card.

Benchmark-wise, it achieves 39 degrees C while idle which is a pretty standard temperature for 1080 cards. Under heavy load however, it reaches up to 73 degrees C. Still lower than the 80 degrees C set by the reference card, but a tad bit higher than what was achieved by some other GTX 1080 cards.

The case lighting can be changed to any color you want, so you can match it to your fan lighting, for example.

The GameRock comes with a G-Panel equipped with a 3.12" LCD display. You can connect it with the supplied USB 3.0 header to the motherboard and it will display information related to the graphics card such as: fan speed, temperature, and memory usage.
